Using custom login button with Twitter Fabric?

Question

I have been trying to use a normal button to execute the authentication process with the twitter sdk but it does not seem to work. Anyone have tried anything similar?

Luis from Developer Relations team at Twitter. Fabric will support theming on the future, meanwhile you can customize the button by creating a custom view that inherits from TwitterLoginButton.

Cannonball sample app implements a custom button:

public class CannonballTwitterLoginButton extends TwitterLoginButton {
    public CannonballTwitterLoginButton(Context context) {
        super(context);
        init();
    }

    public CannonballTwitterLoginButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public CannonballTwitterLoginButton(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init();
    }

    private void init() {
        if (isInEditMode()){
            return;
        }
        setCompoundDrawablesWithIntrinsicBounds(getResources().getDrawable(R.drawable
                .ic_signin_twitter), null, null, null);
        setBackgroundResource(R.drawable.sign_up_button);
        setTextSize(20);
        setPadding(30, 0, 10, 0);
        setTextColor(getResources().getColor(R.color.tw__blue_default));
        setTypeface(App.getInstance().getTypeface());
    }
}

Layout file:

Callback setup:

private void setUpTwitterButton() {
    twitterButton = (TwitterLoginButton) findViewById(R.id.twitter_button);
    twitterButton.setCallback(new Callback() {
        @Override
        public void success(Result result) {
            SessionRecorder.recordSessionActive("Login: twitter account active", result.data);
            startThemeChooser();
        }

        @Override
        public void failure(TwitterException exception) {
            Toast.makeText(getApplicationContext(),
                    getResources().getString(R.string.toast_twitter_signin_fail),
                    Toast.LENGTH_SHORT).show();
            Crashlytics.logException(exception);
        }
    });
}

I strongly recommend you to clone the code and take a look on it.
